Mark Slipknot off that list. Joey broke his ankle.
QUOTE
Slipknot have canceled a number of their European festival appearances as a result of band drummer Joey Jordison breaking his ankle. The following statement was issued on the matter:
"To Our Fans:
It is with huge regret and disappointment that we have been forced to cancel our imminent European festival appearances at Leeds, Reading, 2 Days a Week, Area 4, as well as exclusive performances for MTV Europe and Virgin TV. The other night, Joey Jordison broke his ankle and doctors have advised Joey to stay off his leg for 4-6 weeks to prevent further injury or permanent and more serious damage.
We know you will be hugely disappointed and so are we. Canceling shows is never an easy decision and we apologize to all our fans, friends and family for not being there to throw down with you. We will be back in Europe this November and can't wait to see you all then.
Stay (sic),
Slipknot"
